Definitions

  • This invention relates to couplings for tubular scaffolding.
  • a disadvantage of existing couplings for tubular scaffolding is the difficulty of overhead working when mounting the couplings on standards, and securing the ledgers and transoms thereto, particularly when they are located 6' above previous level.
  • a eoupling comprising in combination, a body member for location around a standard, a wedge ring member which is co-planar and rotatably associated with the body member, and a plurality of pegs, the body member having a central aperture for receiving the standard therethrough and a plurality of radially disposed insets which combine with the wedge ring member to form apertures to receive the pegs therein parallel to the central aperture; the wedge ring member having a wedging surface for engaging the pegs when the ring member is rotated into a wedging position and for disengaging the pegs when the ring member is rotated into a disengaged position.
  • said wedge ring member has a wedging surface which decreases the radial dimension of each radial aperture when the ring member is rotated into a wedging position.
  • the body member is mounted on a standard by means of a pin passing through diametral apertures in the body member and standard.
  • the wedge ring member has diametrically opposed slots in which the ends of the pin are located.
  • said pin is a spiral pin.
  • each peg comprises a shank and a head, the shank having a cross-section for location in the radial aperture and the head having a cylindrical extension extending at right angles to the shank for engaging a tubular ledger or transom.
  • the longitudinal axis of the shank is off set relative to that of the head.
  • the coupling includes a body member or boss 10 having a central cylind- rical passage 12 and four equi-spaced radially extending projections 14 which form between them four insets .16 of substantially U-shape in plan.
  • the web 18 and one side 20 of each inset 16 are at right angles, and the other side 22 forms an angle greater than 90° with the web.
  • a wedge ring 24 is provided to encircle the boss 10 and co-operates with each inset 16 of the boss 10 to provide four equi-spaced radial apertures 30 parallel with the central passage 12 each to receive a peg 32 secured to one end of a ledger or transom as hereinafter described.
  • the wedge ring has on its inner face 26, four radially inward extensions which form wedging surfaces 28.
  • the wedge ring 24 is rotatable about the boss 10, rotation in one direction, i.e. direction of arrow A being the "forward" or wedging direction.
  • the inner face of each wedging surface 28 converges at one end towards the inner face 26 of the wedge ring, i.e. the radial thickness of each wedge decreases towards one end which is the "forward" end relative to the wedging movement of the wedging ring.
  • the inner face of each wedging surface 28 is determined by scribing the inner diameter of the ring but from a centre which is slightly off set from the centre of the ring. As an illustration of this, the surface 28A (Fig. 4) has a radius r and a centre C.
  • the projection forming the wedging surface 28 restricts the rotational movement of the wedge ring between a maximum forward wedging position shown dotted in Fig.2 at F and a maximum rear non-wedging position shown dotted in Fig. 2 at R; such a distance may be, e.g. inch though, when a peg 32 is located in the or each aperture, the wedge ring-rotates forwardly only about, e,g, inch.
  • a peg can be inserted into the aperture when the ring is in or close to the non-wedging position; in a forward position of the ring the peg will be jammed in the aperture.
  • the boss 10 and wedge ring 24 are both mounted on a standard 40 by means of a pin 42e.g.a "spirol" pin which is formed byrolling up a small square or rectangular metal sheet then rolling it up about its longitudinal axis.
  • a pin 42 e.g. a "spirol" pin which is formed byrolling up a small square or rectangular metal sheet then rolling it up about its longitudinal axis.
  • the ring 24, boss 10 and standard 40 have diametrically opposed holes 44, 46, those in the boss passing through a pair of the projections 14.
  • the holes 44, 46 in these three parts are alignable to permit the pin to be forcibly inserted.
  • the pin is of a length such that its ends 48(Fig.2) lie within the wedge ring, so to permit rotation of the ring 24; the diametral holes 46 therein are in the form of slots.
  • a second pair of diametral holes 50 are provided in the wedge ring 24 spaced at 90 to the pin-receiving slots 46.
  • the second pair of holes 50 are round and receives a tool such as a C-spanner by which the ring can be rotated.
  • each peg 32 comprises a shank 60 which is the part locatable in the aperture of the coupling and "a head 62 which has a cylindrical projection 64 extending (rearwards) at right angles to the shank so as to extend radially away from the standard when the peg is located in t-he coupling.
  • the head 62 and. shank 60 both have a flat front face 66, 68, i.e. the side which faces the standard, and the shank has a convex rear face 70.
  • the front face 68 is stepped so that the front face of the head will abut the standard and the lower face of the shank will abut the web in the aperture.
  • a small projection or 'nib' 72 extends from the lower end of the convex face of each peg shank 60.
  • the cylindrical projection 64 of the head 62 is for location in the end of a piece of tubular ledger or transom scaffolding into which it is fixedly secured, e.g. by a spirol pin 74 of smaller diameter than pin 42.
  • each piece of ledger 80 and transom 82 scaffolding has a peg in each end, the shanks of which are in parallel.
  • a number of couplings are connected to a standard 40 each by means of the spirol pin 42 as hereinbevore described; for example, pairs of holes may be pre-drilled in the standard.
  • the pairs of holes in the standard may be spaced at intervals of 1'7 " or metre equivalent along the standard but it will be appreciated that couplings need only be mounted in every other pair, i.d. at 3'3" or metre equivalent intervals.
  • the wedge ring 24 is initially located in the un-wedging position so that a peg can be located in one or more of the radial apertures. When a peg is so located the nib 72 lies below the level of the wedge. ring.
  • the nib 72 of each peg shank increases the holding effect because where the ledger or transom concerned receives an upward force tending to dislodge the peg the nib will abut the lower edge of the ring.
  • the spirol pin 42 prevents such upward force tending to dislodge the ring 24.
  • the boss may have the following dimensions:
  • the wedge ring may have the following dimensions:
  • the double sheer load for such a pin is 5 T 12cwt.
  • the coupling may be welded to the standard or by means of a pin which passes through only the boss and the standard; in these cases, means is provided to retain the ring on the boss, e.g. by a lower ledge on the boss and large headed screws located in the upper face of the boss to overlie the ring.
  • the wedge ring instead of having holes 50 may be provided with a radial projection or nose so that a ring can be rotated by giving the nose a sharp tap with a hammer.
  • the coupling may be pre-positioned on standards to individual or marked requirements.
  • the ledgers and transoms can then be erected by locating their pegs in the four apertures in the coupling and rotating the wedge ring in the "forward" direction, e.g. using the C-spanner or by giving the nose of the ring a sharp tap with a hammer.
  • the parts of the coupling hereinbefore described may be made of metal or alloy such as by drop forging or die castings or shell castings or other material such as reinforced plastics or reinforced glass fibre or combin- at ions thereof.
  • One main advantage of the coupling is the ease of securing ledgers and transoms to it, especially during overhead erecting, because they do not require to be bolted to the coupling.
  • Use of a pin is also advantageous in that the coupling can easily be removed from a damaged standard for re-use or to allow repairs to the standard, or replaced or repair of the coupling.
  • the purpose of such a peg is to compensate for the height between ledgers and transoms in existing scaffolding so that couplings as hereinbefore described may be used in conjunction with existing scaffolding.
  • the pegs can be used with bracings to provide a swivel action facilitating erection of facade bracing; in such a case, tubular braces have flattened ends with transverse apertures in the ends. The cylindrical projections of the pegs located in these apertures and, while being held therein by a pin against removal, they are 'rotatable, thus allowing for angular adjustment of the bracing during erection.
